It's an exhaustive process to be honest. I was invited to three interviews (plus, phone screening). They were all held in three working days in a row (so I had to spare +1h of my current work to attend these interviews). In reality, they could have gathered the three different people that interviewed me in one single day but that's fine. In the end, of this exhaustive process, they told me that I'd hear from them by the end of the week which I never did (no follow-up with the candidates).
